LlNOTYPE-IVIACHINE.

Patented Sept. 19, 1905.

Application filed January 30, 1905. Serial No. 243,368.

provement in Long-Line Attachments for Linotype-h/lachines; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part thereof.

My invention has reference to linotype-machines of the character represented in Letters Patent of the United States No. 436,532. In these machines a composed line of matrices and wedge spacers is transferred to a vertically-movable carrier, known as the first elevator, whereby the line is lowered to the casting position in front of the mold and between two jaws, W'hich confine the line endwise and determine its length when justified or expanded between them by the adjustment of expanding-spacers contained in the line. In the use of these machines it sometimes happens that the operator will set or compose the matrix-line to an excessive length, so that strong pressure is necessary to carry it downward between the confining-jaws. occurs, the resistance of the jaws is liable to displace the matrices at the end of the line, causing defective alinement and other troubles. The elevator which carries the line acts upon the upper end of a vertical rod controlling the driving-clutch of the machine, so that unless the elevator descends to the proper point the machine is prevented from continuing its action. These parts are represented in Letters Patent No. 436,532 by the letters N and (0 respectively.

The aim of the present invention is to prevent the action of the machine in the event of a matrix-line of excessive length, technically known as an overset line and sometimes called a tight line, being presented between the confining-jaws of the machine. To this end I propose to employ a stopping device of any suitable character, to be actuated by the overset lines whenever an attempt is made to carry them downward between the jaws. I prefer to utilize for the purpose a yielding finger, mounted in the jaw'to be acted upon by the end of the descending matrix-line and connected to a stop, which acts to arrest the descent of the elevator, and

When this thereby prevent it from releasing clutch-com trolling devices.

Referring to the drawings, Figure 1 is a perspective view of the right-hand jaw of a linotype-machine with my stop devices connected thereto. Fig. 2- is a front elevation of the same. Fig. 3 is a plan view of the same. Fig. A is a side view of a rock-shaft and arm for actuating the stop device. Fig. 5 is a section on the line :17 y, Fig. 4:. Fig. 6 is a side elevation, from the left, of the elevator carrying the line of matrices, the vise-frame, the line-confining jaws, and adjacent parts. Fig. 7 is a top plan view of the parts shown in the preceding figure. Fig. 8 is an inside face view of the confining-jaws and the intermediate line.

Referring to the drawings, A and B represent the two opposing jaws, mounted in the main frame D for the purpose of confining endwise the matrix line, composed of matrices E and intermediate wedge spacers F, as shown in Fig. 8.

O represents the carrier or first elevator, mounted to slide vertically in the main frame and having at the upper end an overhanging jaw with a vertical channel between its arms 0 c to receive and sustain the matrices E and spacers F. When this elevator O descends from the position shown in Fig. 6, it lowers the line between the jaws, as shown in Fig. 8, in which position the matrices, as usual, stand directly opposite the mold. (Not shown in the drawings.) The aim of the invention is to prevent the elevator G from lowering the ward end with a vertical slot, in which I seata yielding finger Gr, mounted near its middle on a horizontal pivot c and urged forward at the lower end by a spring J, seated in the jaw. The lower protruding end of the finger Gr stands in the path of the descending matrices, so that if the matrix-line is of full or excessive lengththat is, oversetit will press the lower end of the finger (Er backward into the jaw.

- H represents a rock-shaft extended transversely through the jaw and having near the middle a flattened portion in position to be acted upon, as shown in Fig. 5', by a shoulthe space between the jaws.

der on the lower end of the finger G, so that when this finger is pressed inward by the matrices it will act to turn the shaft. The outer end of this shaft is provided with a crankarm I, carrying at its upper end a dog or stop it, the free end of which is extended over the top of the main frame in position to pass beneath a stud or projection K, which I apply to the side of the elevator G, as shown in Figs. 3 and 7. A spring i is extended from the stop-finger h to the main frame and tends to draw the stop-finger h backward out of the path of the stud, so that the elevator C may descend to present the matrix-line in operative position and also depress the rod (0 that the casting mechanism may be set in motion, as usual. If, however, the matrix-line is of excessive length, so that it crowds the finger G backward, the latter will turn the shaft H and its arm I, causing the finger h to be projected beneath the stud K. In this manner the elevator G is prevented from descending far enough to present the matrix-line to the mold or to actuate the rod (L23, and consequently the machine is prevented from operating until the elevator is again lifted and the matrix-line shortened or a new line of proper length presented.

The forward end of the stop-finger h and the side face of the stud K on the elevator are beveled or inclined, as shown in Fig. 2. After a line of proper length is lowered to the casting-level without affecting the finger G in its descent it is elongated or justified, as usual, by lifting the spacers F until it tightly fills When thus elongated, the line actuates the finger G and advances the stop It. The stop is, however, without effect, for the reason that the elevator G and its stud K are already in their lowermost positions, so that the advancing v stop it overrides the stud K and is without effect on any of the parts. Although, therefore, the stop it is advanced each time that a line is presented, it serves to prevent the action of the machine only when a line is of excessive length, so that the finger G is crowded backward during the descent of the line to the casting-level.

The essence of the invention resides in controlling the action of the machine through devices controlled by matrix-lines of excessive length or overset lines.

While I have represented the devices in a satisfactory form for application to commercial linotype-machines, it is to be understood that the parts may be Varied in form and arrangement at will, provided they are oper ated by the matrix-line with the same effect as with the devices herein shown and described.

I believe myself to be the first to operate the stop mechanism of a linotype-machine by or through overset lines or matrix-lines of excessive length.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a linotype-machine, the combination of matrices, means for composing the selected matrices in line, and a stop mechanism having a member arranged in position to be acted upon by thematrix-lines of excessive length.

2. In a linotype-machine, in combination with the first elevator, a stop mechanism therefor, arranged to be actuated by overset matrix-lines.

3. In a linotype-machine, the combination of the first elevator, whereby the matrix-line is supported, and the driving mechanism is controlled, a stop therefor, and a stop-controlling device arranged in the path of the descending matrices, whereby the action of the machine is arrested when an overset matrix-line is presented.

4:. In a linotype-machine, the combination of the elevator to carry the matrix-line, the jaws to confine the line, the yielding finger mounted in one of said jaws, a stop for the elevator and connections between said stop and the yielding finger.

5. In a linotype-machine, in combination with the matrix-confining jaw, the yielding spring-supported finger in position to be acted upon by the matrices, the crank-arm actuated thereby, the stop connected to said arm, and the elevator with which the stop engages.

6. In a linotype-machine and in combination with means for presenting the matrixline to the casting mechanism, a stop acted upon by the matrices to prevent said presentation when the line is overset.

In witness whereof I hereunto aflix my signature in the presence of two witnesses.
